Roundabout Ahead

Roundabout Ahead signs appear 50-150 meters before roundabout junctions throughout Ireland.

Common on approaches to major roundabouts on the M50, N-roads entering towns and cities, junction improvements replacing traditional crossroads, new housing development entrances, and throughout urban areas where roundabouts manage traffic flow.

Ireland has extensively adopted roundabouts as the preferred junction type for safety and efficiency.

Signs often include supplementary lane designation plates.

A roundabout junction lies ahead where traffic circulates clockwise around a central island.

Reduce speed to 30-40 km/h on approach.

You must yield to traffic already on the roundabout approaching from your right.

Select the appropriate lane early: left lane for left turns and straight ahead (exits 1-2), right lane for right turns and U-turns (exits 3-4).

Signal left when passing the exit before your intended exit.

If unsure, use the left lane and navigate carefully.

Failing to yield to traffic from the right at roundabouts constitutes a junction priority violation: 2 penalty points and €80 Fixed Charge Notice.

If failure to yield causes collision, careless driving charges apply: additional penalties and fines to €2,000.

Entering roundabouts at excessive speed causing loss of control results in dangerous driving charges: 5 penalty points, fines to €5,000, imprisonment, and disqualification.

Wrong-way travel (anti-clockwise) on roundabouts results in immediate dangerous driving charges and license suspension.

Roundabout navigation is a fundamental assessment component in both theory and practical tests.

Written questions extensively cover lane selection, priority rules, signaling requirements, and appropriate speeds.

You must know that traffic on the roundabout has priority.

Practical tests include multiple roundabout types.

Examiners assess approach speed (should be 30-40 km/h), correct lane selection based on intended exit, observation for traffic from the right, smooth entry when safe, correct positioning while circulating, and proper exit signaling.

Incorrect lane choice, failure to yield, or excessive speed results in Grade 2-3 faults.
